Natural white grow light

The white spectrum of approximately 4200–4500K approximates daylight and supports vigorous vegetative development. This results in compact plants with a sturdy structure.

High light output

The lamp delivers powerful light intensity and is suitable for medium-sized grow rooms where a reliable grow lamp is desired.

When to replace?

Although the lamp technically lasts approximately 15,000 to 20,000 burning hours, the light output gradually decreases. For optimal growth performance, we recommend replacing the lamp after approximately 8,000 to 10,000 burning hours.
